Abstract

PURPOSE:To make control cranes and the like with high performance and stability, by outputting an effective correction signal based on the figures at present and in the past. CONSTITUTION:A position shift signal from a position shift detector 7 is A/D converted 10 and stored in a computer 11. Further, an extent of position shift elapsed for a prescribed T seconds is fetched and it is stored as a new extent. Further, the difference between the figure for T seconds and the figure fetched at present is discriminated to obtain the extent of position shift changed for T seconds, and the magnitude difference between this and the specified permissible value is discriminated. If it exceeds the permissible value, a correction signal is fed to relays 12 and 14 switching the fields of DC motors 1, 2 fitted to opposing crane legs. This correction signal is output until the extent of correction change to the induction line 8 of the crane for T seconds is a prescribed value.
